    Hi everyone,

    The Router: Linksys WRT150N (draft N)
    The Computer: 2007 C2D 2.33 Ghz Macbook Pro (with wireless N update installed)

    The problem:

    When the router is set to Wireless-N only, the download speed is extremely slow (roughly 600kbps). The upload speed is around 4000kbps. The connection strength is "excellent".

    When the router is set to Wireless-G only, the download speed is great (15000kbps) as is the upload speed (4000kbps). Again, the connection strength is "excellent".

    This problem persists in both OSX and Windows XP.

    You may be asking, if G works great, why am I complaining? The answer is that I would like to stream HD content to my PS3, and G just isn't cutting it.

    Anyone have any thoughts? I've tried pretty much every combination of channels and radio bands. The radio bands supported by this router (for draft N) are Standard 20 Mhz and Wide 40 Mhz. The channels are all around 2.4 ghz.

    If anyone has any advice, I would GREATLY appreciate it!

    Thanks awesome people.

    Edit: I have the latest firmware installed on the router

    Hold down alt/option key and click your Wifi symbol in your top bar while running on N in OS X and tell us what the transmit rate, RSSI, and channel says.
    You should get about 48-60 G and about 130-155 N

    That is SWEET. Thanks for the information. I can now confirm that my Airport Extreme (802.11G) is running 54mbps as I'd imagined.

    OK, when it's set up as a Wireless-G only network, I get:
    Channel: 9
    RSSI: -56
    Transmit Rate: 54

    Wireless-N only (20 Mhz radio band):
    Channel: 9
    RSSI: -56
    Transmit Rate: 117 to 130

    Wireless-N only (40 mhz radio band):
    Channel: 9
    RSSI: -54
    Transmit Rate: Fluctuates, 19 to 78 or so.

    Does this explain anything?

    I have the same exact problem with the same router. Was there ever a solution for this?

    install dd-wrt on your router and call it a day

    in dd-wrt up the broadcasting strength and set to n/g or whatever you want it and then you can stream 5 hour 1080p HD movies for all it matters and they'll work just fine

    If you can use opensource firmware do it. I would recommend Tomato.

    I have DD-Wrt running on my Linksys WRT150N, works great.

    Now just wish they could get a stable version out for Netgear WNDR3700. :p

    I have been googling/testing my wireless for a week now and I have this same exact problem with this same router. My new N wireless computer couldn't even stream 480p youtube, while my old G wireless computer could.

    As soon as I switch the wireless setting to G-only everything worked fine. I will be looking to download this dd-wrt program to take full advantage of my N wireless soon.
